Sommario/riassunto

There has been significant expansion in the application of atomic spectrographic techniques in recent years, which has brought with it the need to provide more flexible methods to a wider range of samples, particularly non-aqueous samples. This book compares the traditional and improved methods in the analysis of non-aqueous samples for elemental analyses by atomic emission spectroscopic methods whilst describing procedures that will attempt to improve sample preparation methods.
